Yes, that's my question. If someone wanted to follow NEC (and I agree, this is not required) one could use something like General makes, much smaller and lighter. That's my very question...why not use one conductor?
With regard to the proximity question, I'm not entirely clear how you...
Here's an article that discusses exactly that question

Note below that in the special cases where wires smaller than 1/0 are permitted, they require that each individual conductor be able to carry the entire load. They are...
Right, if you are not pushing the capability it doesn't matter. But most of the discussion seemed to relate to how hard can one push it? Is it safe at so many Amps. I'm simply saying 4 fifteen-Ampere wires in parallel don't equal a 60-Ampere wire. And it's better to use a single...
I'm a little surprise that either one of you is relying on multiple parallel conductors to provide the necessary capacity. This is generally not good practice since
1. It is difficult to assure that the current is equally shared, resulting on some conductors being stressed, and
2. If one...
